On the other hand, since the pedestrian passage guide 800 according to the second embodiment of the present invention is formed integrally with the joist line 811, the flooring 820 and the anti-slip flooring 830, The above-described problems can be solved by bringing the forklift 800 into the bracket immediately after bringing it to the construction site.

Here, the anti-slip flooring 830 includes, for example, an amorphous thin high-strength elastic aluminum yarn foamed as a solid line on the upper surface, a waste aluminum plate having a trench shape formed concavely in the center of the lower face, A non-slip floor having a reinforcing steel plate which has a cross section corresponding to the profile of the outer and lower surfaces of the bottom plate and engages with the waste aluminum plate can be used.

The waste aluminum plate can be used by recycling aluminum plates already used in other industries. Further, by forming the anti-slip floor by combining the aluminum plate and the reinforcing steel plate, the reinforcing steel plate acts as a strong footing plate of the flooring material, and is made of an elastic material having amorphous thin and high strength elastic aluminum yarn It acts as a packing material on the road surface, which is not hurt when the waste aluminum plate falls down.

As described above, since the anti-slip flooring according to the second embodiment of the present invention is formed by closely forming amorphous thin high-strength elastic aluminum yarn foamed in solid line on the upper surface of the wasted aluminum plate, It is effective not to be hurt even if it falls down from the road surface of.

Further, the anti-slip floor according to the second embodiment of the present invention further comprises rubber between the inner surface of the trench and the corresponding end surface of the reinforcing steel plate, and the cross section of the reinforcing steel plate corresponding to the lower surface of the waste aluminum plate A plurality of through holes are formed.

As described above, since the rubber is sandwiched between the inner surface of the trench and the end surface of the reinforcing steel plate corresponding thereto, there is an effect of reducing the friction sound generated between the waste aluminum plate and the reinforcing steel plate.

Further, since a plurality of through holes are formed in the end surface of the reinforcing steel plate corresponding to the lower surface of the waste aluminum plate, there is an effect that the rainwater permeating between the plurality of bottom materials is not accumulated and drained during rain.

Also, unlike the synthetic wood, the anti-slip flooring material 830 according to the present invention has an effect of not decaying even when it rains, and unlike the polyurethane, it is not peeled or broken.

Moreover, since the waste aluminum plate used as the anti-slip flooring material 830 according to the present invention is used by recycling an aluminum plate already used in other industrial fields, unlike the synthetic woods used in the past, it is eco-friendly and can be used permanently Can have excellent effect. The anti-slip flooring using such waste aluminum can be confirmed in detail in Korean Patent No. 10-1122681 obtained by the present applicant.

Of course, other anti-slip flooring may be used in addition to the anti-slip flooring using the above-mentioned waste aluminum yarn.
